SPECIFICATION forming part of Letters Patent No. 524,743, dated August21, 1894. Applica ion fil April 4, 1893. $erial No. 469.055. (No model.)

To all whom it may concern.-

Be it known that I, CARL voN PECKER, a subject of the Emperor ofAustria-Hungary, residin g at Vien na,Austria-Hungary, have invented newand useful In] provements in Hand Firearms, of which the following is aspecification.

The object of this invention is to provide a fire arm especially arevolver, having such parts and mechanism that a series of double shotsor a series of single shots (twice in number as the series of doubleshots) as desired can be fired off; the firearm is simple, durable andstrong in construction as well as accurate and reliable in operation.

The invention consists in the improved fire arm, in the arrangement oftwo series of cartridge chambers in the cylinder, in the mechanism forfiring the cartridges singly or in series of two, and in the combinationand arrangement of the various parts hereinafter more fully describedand claimed.

Similar letters and figures of reference in dicate corresponding partsthroughout the several views.

Figure l is a longitudinal section, partly broken away, on the linecca:, Fig. 5. Fig. 2, 1s a similar section on the line yy, Fig. 7. Figs.3 and 4 are respectively left and right side elevations of the fire arm,partly broken away. Figs. 5, 6 and 7 are cross sectional views on thelines zz, 'uo and w-w, respectively of Fig. 1, taken in the direction ofthe arrow 10. Figs. 8, 8, 8 8 and 8 are detail views of the firing pinsof the firearm illustrating certain positions of the same. Figs. 9, 9, 9and 9 are detail views of the cylinder containing the cartridges,illustrating various positions assumed by the same in firing. Figs. 10,10 and 10 are respectively front, side and rear views of the lockingdevice for the firing pins. Fig. 11 represents details, in side andfront elevation of the construction of the firing pins. Figs. 12, 12 and12 are respectively front, side and top views of the trigger and Fig. 13is an end elevation of the hammer.

In said drawings A represents the axis in form of a screw around whichturns the disk B, carrying the firing pins 1, 2, 3 and 4. The disk B isprovided with a circular groove 19 in which is arranged a spiral springF, one end of which is secured as at b to said disk B, while the otheris secured to a pin 19 0f the frame of the firearm. The firing pins 1,2, 3 and 4 rest against two similar pins or a controlled by spiralsprings a. The firing pins 1, 2, 3and 4t transmit the action of thehammer H and also of its flattened surface it through the pins or to thefulminate cap of the cartridges P and are returned by the springs a,after firing, into their normal position. The respective arrangement ofthe pins 1, 2, 3 and 4 and a, a is such, that the pins or a are arrangeddiametrically opposite to each other, while the pins 2 and 3 are placedon either side of and separated from pin 1 by a quad rant of the disk,and the pin 4 one eighth of said disk from the pin 3. By thisarrangement, when the disk is turned, the firing pin 1 may be broughtopposite and in contact with the lower pin a or the pin 4 in contactwith the upper pin a or else both pins 2 and 3 in contact with both-pinsa, a. Thus either the cartridges in the upper or lower chamber may bedischarged singly or both may be discharged at once.

To move the disk B and to register it in its proper position toaccomplish the above described operations, its periphery is providedwith three notches or teeth 0, c and c engaged by a tooth or pawl 0arranged on a lever D pivoted on the frame of the firearm as at C (seeFigs. 5 and 6). I

The cylinder T is provided with two annular sets of cartridge chambers PP which register with the barrels L L arranged in the same verticalplane. The cylinderT is moved forward in the ordinary manner after eachdischarge and the movement of the cylinder backward between shots isprevented by the engagement of one or the other of the two projectionszz' of the trigger Z which enter suitable recesses i in the cylinder.When the barrel is to move forward, these two projections zz' lie in thesame horizontal plane and thus clear the notchesor recesses t. Thecylinder T is also provided on its inner periphery with a pin orprojection E for the purpose hereinafter described. On the top of thebreech ofthe fire arm that is to say directly above and behind the innerend of the cylinder are arranged the two projections f f forming betweenthem a recess adapted to receive the thumb piece f controlled by thefiat spring f. This thumb piece f is raised from the recess when therevolver is to be adjusted for firing as hereinafter described and whenso adjusted it is afterward low-' ered. Secured to the barrel below thethumb piece is arranged the spring piece l3 which normally extendsinward and downward to come directly into the path of the pin orprojection E on the cylinder T and to thereby stop the rotation of saidcylinder. The arrangement of this pin E on said cylinder and itsrelation to the cartridge chambers is such that when it rests againstthe spring F one of the cartridges in the inner as well as outercartridge chamber is in position to be discharged. The spring piece E isin its nor- 7 mal position only when the thumb piece f 7 piece.

is raised from its recess. When the thumb piece f is lowered, the springF is pushed out of the path of the pin E by means of the inclinedsurface f carried by said thumb The leverD carries also a projection Gwhich lies in the path of the pin E and is adapted to be depressed bysaid pin when said pin and projection come into engagement. Thedepression of this projection G actuates the lever D and therebywithdraws the tooth G from engagement with the notches on the peripheryof disk B.

The operation is asfollows:If the cartridges of the inner chamber are tobe discharged the thumb piece f is lifted and the cylinder T turneduntil the pin. E rests against the spring F The disk B is then turneduntil the pin 1 and the lower pin a are in line in which position the.tooth O of lever D slips into one of the notches'of the disk B and saiddisk is thereby locked in said posi-.,

tion. This position of the disk is its normal one and is indicated atFig.5. The thumb piece) is now lowered and the spring F crowded out ofthe path of the pin E on the cylinder. The fire arm is now dischargedshot by shot until all the cartridges-of the inner chambers are empty.

To fire off the outer circle of cartridges the same operation is gonethrough with as above described only in this case the disk B is movedagainst the action of spring F until the pin 4 and the upper pin a, arein line. The position of the disk in this case is indicated at Fig. 8.

action of the firing pin, the pin E passes on to the projection G oflever D and thereby depresses the lever D and lifts the tooth C out ofthe second notch in the periphery of disk lhe disk B now by virtue ofspring F returns to its normal position (see Fig. 5)

that is the position when the lower firing pin a and pin 1 are in line.The inner cartridges are then discharged successively.

To fire off double shots the disk B is turned into the position shown atFig. 8 in which the pins 2 and 3 are respectively in line with the upperand lower pins or a.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is.

1. In a revolver the combination with the revolver frame, the cylinderand the hammer, of a revolving disk interposed between the hammer and.the cylinder and provided with a circular groove, a spiral spring insaid groove and secured with one end to the disk and with the other endto the revolver frame, said disk being also provided at its outerperiphery with teeth or notches, a series of spring controlled firingpins in said disk, pins adapted to be operated by the hammer to operatesaid firing pins, and a lever provided with a tooth and adapted toengage the' notches of said disk, all parts, substantially as and forthe purposes set forth.

2. In a revolver, the combination with the revolver frame, thecylinderand the hammer, of a revolving disk interposed between the cylinder andthe hammer, a lever pivotedto the frame and provided with a toothengaging said disk, and a pin secured to the rear end of the cylinderfor releasing said lever, all said parts, substantially as described.

3. .In a revolver the combination with the revolver frame, thecylinderand the hammer, of a revolving disk interposed between thecylinder and the hammer,-a series of firing pins in said disk, pinsadapted to be operated by the hammer to operate said firing pins, alever pivoted to the frame and provided with a tooth engaging said disk,a pin secured to the rear end of the cylinder for releasing said leverand a spring provided with a projection adaptedto engage said pin andthus limit the movement of the cylinder, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
